Short answer: this is Almost Heaven’s portable Bluetooth speaker for saunas, sold on Amazon. It runs 8 hours on a charge, charges over USB-C, and two can be paired for stereo. The listing calls it heat resistant and waterproof but gives no temperature limit and no IP rating, so read the manual before leaving it in a hot cabin.
What the listing gives
A 4” x 4” x 8” speaker weighing 12 oz, in black or red. Almost Heaven, which also builds sauna cabins, sells it for traditional and infrared saunas, wet or dry, indoors or outdoors.
What it leaves out
Here’s what the spec sheet won’t tell you: how hot it can get. “Heat resistant” without a number means you can’t compare it with your sauna’s top temperature. A traditional sauna runs much hotter than an infrared cabin, so this matters most there.
There’s also no IP rating to back the “waterproof” in the title. Check the manual for what it says about steam before placing it near the stones.
Where it fits
Infrared cabins often have built-in audio, like the Durasage 2-Person. Most barrel and indoor traditional saunas don’t. A portable speaker is the simplest add-on, with nothing to wire.
Bottom line: a sensible pick if your sauna has no audio, once you’ve confirmed the temperature limit in the manual. Amazon sets the price. See Sauna Accessories Worth Buying for where it ranks.
